Differences in lower quarter Y-balance test with player position and ankle injuries in professional baseball players.

Purpose: Although there has been research about the correlation between ankle injury and Y-balance test (YBT) conducted in other sports, there has been a lack of research on the correlation between ankle injury among baseball players and YBT scores or on differences in scores according to baseball positions. This study focused on professional baseball players as its subjects with the aims of analyzing the correlation between YBT and ankle injury and assessing differences in YBT between baseball positions.

Methods: Age, height, weight, body mass index, and spine malleolar distance of 42 professional baseball players were measured.

Results of tenorrhaphy with early rehabilitation for acute tear of Achilles tendon.

Background: For the treatment of acute Achilles tendon rupture, early rehabilitation after surgical repair is believed to be a useful method. The purpose of this study was to evaluate the outcome of open tenorrhaphy followed by early rehabilitation.

Methods: A total of 112 patients who underwent open repair and early rehabilitation for acute Achilles tendon rupture from January 2003 to March 2015 were retrospectively reviewed.

Ultrasound-Guided Hyaluronic Acid Injection for the Management of Morton's Neuroma.

Background: Morton's neuroma is one of the common causes of forefoot pain. In the present study, hyaluronic acid injection was performed on patients to determine the efficacy and adverse effects of hyaluronic acid in management of Morton's neuroma.

Methods: Eighty-three patients with Morton's neuroma in their third intermetatarsal space with definite Mulder's click were included in the study.

Diabetic Foot Complications Despite Successful Pancreas Transplantation.

Background: It is known that successful pancreas transplantation enables patients with diabetes to maintain a normal glucose level without insulin and reduces diabetes-related complications. However, we have little information about the foot-specific morbidity in patients who have undergone successful pancreas transplantation. The purpose of this study was to investigate the prevalence and predisposing factors for foot complications after successful pancreas transplantation.

Rat odontoblasts may use glutamate to signal dentin injury.

Accumulating evidence indicates that odontoblasts act as sensor cells, capable of triggering action potentials in adjacent pulpal nociceptive axons, suggesting a paracrine signaling via a currently unknown mediator. Since glutamate can mediate signaling by non-neuronal cells, and peripheral axons may express glutamate receptors (GluR), we hypothesized that the expression of high levels of glutamate, and of sensory receptors in odontoblasts, combined with an expression of GluR in adjacent pulpal axons, is the morphological basis for odontoblastic sensory signaling. To test this hypothesis, we investigated the expression of glutamate, the thermo- and mechanosensitive ion channels transient receptor potential vanilloid 1 (TRPV1), transient receptor potential ankyrin 1 (TRPA1), and TWIK-1-related K+channel (TREK-1), and the glutamate receptor mGluR5, in a normal rat dental pulp, and following dentin injury.

Femorotibial relationship changes as the posture changes from patellae-forward stance to preferred toe-out stance.

Background: Full-length standing anteroposterior radiograph is a standard protocol to evaluate the lower limb alignment in frontal plane. However, most people tend to stand or walk with feet pointing outward. The purpose of this study is to assess the femorotibial relationship as the posture changes from patellae-forward stance for the conventional technique of a full-length standing anteroposterior radiograph to a toe-out quiet stance using a fluoroscope.

Treatment of Intertrochanteric Fractures Using the Compression Hip Nail.

Purpose: To investigate the clinical and radiologic outcomes following treatment of intertrochanteric fractures using the Compression Hip Nail® (CHN), which has a sliding lag screw.

Materials And Methods: Twenty-eight cases of intertrochanteric fractures treated with CHN from November 2012 to October 2013 and followed-up for >6 months were included. The patient population consisted of 11 men and 17 women with a mean age of 75.
